This set has been in a closet for many years and I just re-discovered it. No one in my family knows anything about these, but I tried to look up as much as I could. It has a 61572 engine and coal car with the old logo.Also a milk tank wagon, a flat car, a box car and a caboose. Comes with 8 11" curved train tracks and 2 7" tracks. It has an RP 15 power controller also, and some directions - see pictures I guess the engine makes noise and does fun stuff if you know how to make it work! I'm not sure how to tell the condition since I don't know anything about it - see pictures. As far as I can tell they are in good condition.
Let me know if there is anything else I should list about them. They all say made in England.
The engine has a small bit of rust on the wheel bar, and the milk truck has one tiny bit of a black bar broken off - you can see it in the picture that shows the ends of the cars. Also I tried to see if it runs, and I couldn't get it to go, but it has been sitting so long, and some of the instructions say to be sure they are oiled, which I have no idea how to do. Also there may be an on/off switch or something that I just don't see.
If anyone has any advice as to what I might try, let me know, or I can send more pictures!
